Webcam Setup help andvise needed

I have never messed with webcams before but the family over in England has one now and we want to chat via cam on it.
what do I need to do to get this up and running.
I know That I need a cam with a 30fps rate but that's about it.
How does this work?

I'm not sure I understood the question correctly, so sorry if I didn't. Installing a webcam is very easy. It's usually just plugging the cam in, installing the drivers supplied on the cd, maybe adjust the microphone volume a bit(if you have one with microphone included at least) now you can use a few programs to chat via the webcam. Most commonly used are MSN and Skype, but there are tons more. Big chance you already have one of those programs on your pc though.
